FEATURE: Native app banner improvements This commit adds some improvements to native app banners for iOS and Android - iOS and Android now have separate settings for native app banners - app banners will now only show for users on TL1 and up - app ids are now in a hidden site setting to allow sites to switch to their own app, if desired - iOS only: the site URL is passed to the app arguments 2019-04-18 00:25:13 +08:00			`<%- if include_ios_native_app_banner? %>`
FIX: only use app argument for official iOS app banner When showing the native app banner, we include an app argument to automatically add the current site to the official DiscourseHub app. However, the app id can be changed via a hidden site setting, and when changed, that argument is no longer useful. This ensures the argument is only included for the official iOS app banner. 2019-08-27 22:23:57 +08:00			`<meta name="apple-itunes-app" content="app-id=<%= SiteSetting.ios_app_id %><%= ios_app_argument %>">`

FEATURE: Native theme support This feature introduces the concept of themes. Themes are an evolution of site customizations. Themes introduce two very big conceptual changes: - A theme may include other "child themes", children can include grand children and so on. - A theme may specify a color scheme The change does away with the idea of "enabled" color schemes. It also adds a bunch of big niceties like - You can source a theme from a git repo - History for themes is much improved - You can only have a single enabled theme. Themes can be selected by users, if you opt for it. On a technical level this change comes with a whole bunch of goodies - All CSS is now compiled using a custom pipeline that uses libsass see /lib/stylesheet - There is a single pipeline for css compilation (in the past we used one for customizations and another one for the rest of the app - The stylesheet pipeline is now divorced of sprockets, there is no reliance on sprockets for CSS bundling - CSS is generated with source maps everywhere (including themes) this makes debugging much easier - Our "live reloader" is smarter and avoid a flash of unstyled content we run a file watcher in "puma" in dev so you no longer need to run rake autospec to watch for CSS changes 2017-04-12 22:52:52 +08:00			`<%= theme_lookup("header") %>`
